Hey guys, I got a 96 12v puller that i have taken the wiring harness out of the truck has been a work in progress and I'm hoping to pull this weekend for its first time. My question is i have a tach that i had in my old mud truck it was a gasser. Can i wire it in to the factory pick-up sensor, it's still in place, and if so which wire do i need to hookup? Any help appreciated, thanks!
